Introduction of BIOS 3-17
(4) Chipset Features Setup Menu
The Chipset Features Setup Menu is used to modify the contents of the buffers in
the chipset on the motherboard. Since the parameters of the buffers are closely
related to hardware, if the setup is not correct or false, the motherboard will
become unstable or you will not be able to boot up. If you don’t know the
hardware very well, use default values ( i.e. use the LOAD SETUP DEFAULTS
option).

You can use the arrow keys to move between the items. Use PgUP , PgDn , + or -
key to change the values. When you have finished setting up the chipset, press
ESC to go back to the main menu.
SDRAM CAS latency:
When synchronous DRAM is installed, you can control the numbers of CLKs
between when the SDRAMs sample a read command and when the controller
samples read data from SDRAMs. You can select SDRAM CAS (Column
Address Strobe) latency time according to your SDRAM specification.
SDRAM precharge control
When enabled, all CPU cycles to SDRAM result in an ALL Banks Precharge
Command on the SDRAM interface.
